I doubt you have them, if you do you would see grease fittings in the end of each suspension bolt. What you have is plastic bushings, nylon I think. Mine were worn thin from the trip from factory to the dealer. Wetbolts come with bronze bushings and you can grease them with a grease gun.
Is it better?
I had a lot of popping noise from the suspension, that is all gone. With the worn plastic bushings my axles were sloppy once I jacked the trailer off the ground. With the wetbolts the axles pivot up or down but not all over the place.
The down side is you have to remember to add some grease where with the plastic bushings you don't.
